Application filed December 13, 1919. Serial No. 344,553.

To all whom it may concern Be it known that I, STERLING H. CAMP BELL, acitizen of the United States of America, residing at the city of St.Louis, State of Missouri, United States of America, have invented acertain new and useful Uncoupling Device, of which the following is sucha full, clear, and exact description as will enable any one skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanydrawings, forming part of this'speciiication.

My invention relates to an uncoupling device such as is used to operatethe locking pin of a coupler of the vertical plane type to release theknuckle.

In the accompanying drawings which illustrate an uncoupling device madein ac- 24) cordance with my invention together with a portion of arailway car to which the same is applied, Figure 1 is a front elevation,2 is a top plan view, Fig. is an enlarged plan view of some of the partsshown in Fig. 2, Fig. & is an enlarged front and supported in a bracket17. The lever 15 is provided with an extension 18 passing through theeye of the coupler pin 13 and provided with a return bend 19 preferablyformed in a horizontal plane so as not to project above the top of thepin 13. The

extension 18 is provided with a pair of apertures 20 and 21respectively, as best shown in Fig. 3. The extension is secured to themain lever 15 by means of a bolt or rivet 22 passing through the saidlever and through the opening 20 in the extension. The end of theextension 18 is preferably curved at 23. The main part 15 of the leveris provided with a projection 24 extending a;

anc passing through the opening 21 which is somewhat elongated in formto allow the necessary lateral movement between the body of the leverand the extension. The 2& is provided with an upturned end 25 forlimiting the lateral movement of the extension.

In Figs. 6 and 7, I have shown a modifi' cation in which the extension18 is provided with a single slot 26 adapted to receive a flatprojection 24%. The shape of this projection serves to hold theextension against rotary motion. A rivet 27 limits the lateral movementof the extension in this modification.

The bracket 17 is secured to the side of the car 10 by any suitablemeans such for instance as bolts or rivets 28 and is provided with avertical slot 29 adapted to receive the lever 15 and to allow itsmovement in vertical plane. The lever 15 is provided with a recess 30adapted to bear on the curved bottom 31 of the slot 29. In order to holdthe lever in operative relation to the curved bottom 31, I provide thebracket with a pair of lugs 32 as best shown in Fig. 3. The lugs arecast in the form shown in dotted lines in this figure and are adapted tobe bent around a locking pin 3 1. The pin 3 1 is adapted to be swungacross the open top of the slot 29 to lock the lever in position. Thepin 34 is provided with a head 37 and is locked in position by spreadingthe two parts of the slotted end. In this way, the parts are securelylocked together but the lever may bending the parts of the slotted endtogether and swinging the bolt 34: on its pivots. At the same time thereare no parts which may become lost so as to disable the device.

The operation of my device will be evident. The locking pin 13 is raisedby depressing the handle 16 so as to swing the lever 15 in a verticalplane and at the same time the necessary movement between the couplerhead and car is provided by the sliding of the extension 18 in the eyeof the locking pin and by the lateral movement between the extension 18and the body 15 of the lever.

Having fully described my invention. what I claim as new and desire tosecure by Letters Patent of the United States is:

1. In an uncoupling device, the combination with an operating leverhaving a main part provided with an angular projection, of a bracketcarrying said lever, an extension permanently secured to said main partand provided with an aperture through which said he released by angularprojection passes,

whereby the lever must he removed from the bracket to disengage theextension from the coupler eye.

2. In an uncoupling device, the combination with an operating leverhaving a main part provided with an angular projection,- of an extensionhavlng a curved end lying against the front face of said main part andprovided with an aperture, fastening means passing through said apertureand securing said extension to said member in rocking relation thereto,and a secondaperture intermediate of the length of said extension thefront face of said lever in rocking relation thereto and provided withan aperture through which said angular projection passes. e

In testimony whereof I have hereunto set my handand afiiXed myseal.
